I am implementing a file picker which allows users to select a .mid file stored on iPad. These midi files contain patch libraries for the Virus TI synthesizer. I think they have kind of syses data inside.
I have set the documenttype for the document picker to ["public.midi-audio"]. IT shows the midi files correctly and it allows me to select them.
Now the problem: When I test my app in simulator, as soon as I select a mid file, the didPickDocumentsAt function s not called. Instead an error message pops up:
Couldn't communicate with a helper application
Try your operation again.If that fails, quit and relaunch the application and try again.
I do not understand this message since my own app should be the helper application?
Now I wonder, is this error related to how the document picker performs within a simulated iPad. Or is it related to my code, or the selected files? Any thoughts on this would be highly appreciated!
